Abstract

L'invention concerne un circuit de répartition du courant destiné à un dispositif de communication, tel qu'un circuit téléphonique d'abonnés, composé d'une première dérivation d'absorption de courant, reliée en parallèle à une deuxième dérivation d'absorption de courant. Ces deux dérivations absorbent au moins le courant continu présent sur la ligne téléphonique, tandis qu'une surintensité de courant dans la ligne de courant continu est absorbée par la deuxième dérivation d'absorption de courant, cette deuxième dérivation étant dotée d'un transistor d'absorption de courant dont le collecteur et l'émetteur ont une tension relativement importante. Ceci permet de réduire l'encombrement du microcircuit effectivement nécessaire. Le courant continu de ligne peut être mesuré à l'aide d'un filtre passe-bas, qui sera de préférence relié à un miroir de courant.
